Title: Deflection of harmful radiations - used against e.g. gamma rays, emanating from underground water sources
Inventor: BUSENBACH PETER
IPC: A61N1/16
Filed: 1973-12-28
Abstract: Harmful radiations from underground water sources, which penetrate buildings in a vertical direction, are deflected by laying electrodes perpendicular to the direction of flow of the water, in building e.g. in the cellar or any floor. Conventional welding electrodes are used with a core of Ni or other metal, having a length of approx. 50 cm. A water divining rod is used to determine the position and direction of flow of the water, and the electrode is placed on the inside of an outer wall of the building, dividing the area affected into two zones, one penetrated by radiations and one including the building, free from radiations.

Title: Electron beam energy detector for particle accelerators - measures electron time in accelerating field using detector and clock pulse counter
Inventor: MEYER RUDOLF
IPC: G01T1/29
Filed: 1974-12-16
Abstract: The electron beam energy detector, for particle accelerators (eg betatrons and linacs), measures the electron acceleration time and uses this as a basis for indicating the energy of the emerging beam. A first signal (9) is generated that characterises a given accelerating field distribution and the time between this signal and a signal received from a particle detector (7) at the accelerator output is measured by counting clock pulses (17). Fluctuations in the accelerating field are taken account of by a coil (36) in this field and coupled to the input of a voltage frequency converter that acts as the pulse generator.

Title: Domestic coffee making machine - is fitted with electrically operated indicator to show when coffee is ready for serving
Inventor: NEUBAUER HORST DR
IPC: A47J31/54
Filed: 1975-07-23
Abstract: The coffee making machine has a cold water tank connected by a pipe to a heater tube. The heated water flows upwards through the pipes and into filter and then drips into the container. The water is heated by means of the electric element. NTC resistor is fitted in a circuit parallel to the heating element. When the thermostat switches off the heating element, a small current flows through the NTC resistance. The consequent temperature rise reduces the value of that resistance. The current therefore slowly increases until it is sufficient to operate the 'coffee ready' indicator. The delay in operation of the indicator allows time for the coffee or percolate through the filter.
Patent DE-2547382-A1 (DE)
Title: Pulse propagation time measurement - is based on propagation time measurement of light pulse emitted by laser diode
Inventor: ELISEO RIO
IPC: G01S17/18
Filed: 1975-10-23
Abstract: An electric signal is applied to the noninverting input of a differential amplifier (26). Its magnitude depends on the current propagation times tripped by the laser pulses in a transmitter (10) and receiver (29), and on the actual propagation time of the laser pulse. A fixed value signal (27) is applied to the amplifier (26) inverting input, whose magnitude depends only on the current propagation times in the transmitter (10) and receiver (29), so that an amplifier (26) output delivers a signal depending only on the propagation time of the reflected light pulse.

Patent DE-2557656-A1 (DE)
Inventor: KANDLER JOACHIM DIPL CHEM DR
IPC: C02F1/52
Filed: 1975-12-20
Abstract: For purifying dye effluents by means of chemical flocculants, a chlorinating agent is added in a first stage to the dye effluent, a divalent iron salt is then added and subsequently the pH is adjusted to a value between 5.0 and 7.0 and the precipitated iron hydroxide is removed. This process allows in general a virtually complete removal of the dye from the effluent. At the same time, the COD and BOD5 value are normally greatly reduced, whereby a substantial release of the biological water treatment plant is effected.
